DISPENSING DEVICE.

Application filed December 5, 1916.

To all 'whom t may concern.'

Be it known that l, WILLIAM C. STEWART, a subject of the King of England, residing at Swampscothin the Vcounty of `Essex and State of Massachusetts, have invented certain Improvements in Dispensing Devices, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts inthe several figures.

This invention relates to a dispensing device and especially to such a device adapted for use with inflammable fluids so as to prevent danger from fire.

Most sorts of liquid cement for use in cementing leather, rubber and the likeare highly inflammable and if exposed in an ordinary receptacle they deteriorate and are liable to catch fire.

The general object of this invention is to provide a receptacle for use with such fluids which shall protectthe user and surround* ing material from the danger of lire. A further object is to devise a barometric dispensing device which is provided with an improved brush cup. U

rlhe invention will be more readily understood from the following specification taken in connection with the accompanying drawings, in which- V Figure 1 is a side elevation of the improved dispensing device;

Fig. 2 is a detail of the retaining latch for the spring-pressed cover; and

Fig. 3 shows a modified form of' the receptacle and the latch.

The barometric dispensing receptacle illustrated in Fig. 1 will be seen to comprise an airtight main receptacle 10 normally supported upon feet 12 and 14 and provided with an auxiliary receptacle 16 which communicates with said main receptacle at a point 18 below the normal level of the fluid in the auxiliary receptacle. Similar constructions are well known in the art and their operation need not be further ex plained. In order that the user and adjacent inflammable material may be protected in case the fluid in the auxiliary receptacle ignites, a cover 2O is pivoted on the main receptacle and is pressed downwardly to close the auxiliary receptacle by means of a spring 22. This cover may be retained in open position by means of a latch arm piv Specification of Letters Patent.

oted to a lug 24 and made up of two members 26 and 28 between whose outer ends is mounted a retaining linger 3G. rlhis finger is pivoted within said arms upon a pivot 32 but is normally held in the position, shown in full lines in the drawing, by means of soft solder having a low melting point between the member 30 and said arms. The arm 26 is preferably provided with extensions, as shown in Fig. 1, to limit its movement upon the lug 24. `When the cement or other fluid in the receptacle ignites, the heat caused thereby will melt the solder and allow the member 30 to rotate to the position shown in dotted lines in Figs. 1 and 2, thereby releasing the cover 20 which will be closed by the action of the spring 22. Obviously, this spring may be omitted and the action of gravity relied on if desired. Vhen it is desired to fill the receptacle, it will be rotated clockwise and supported upon the leg` 12 and the lug 34. VCement or other fluid may then be introduced through the auxiliary receptacle 16 to fill the main receptacle. The opening of' the auxiliary receptacle 16 is preferably divided by a partition whose lower edge is shown in dotttd lines at 3d so that during the filling of the receptacle with a viscous fluid the throat 18 will not be choked and a free escape of air from the main receptacle allowed.

It is common in such devices to provide a cup which may be filled with water for the reception of the brush used with the fluid dispensed by the receptacle in order to keep the brush in good condition. If such a cup is provided upon a barometric dispensing device, it will obviously be open to the objection that its contents will be spilled when the receptacle is partially inverted for filling. Accordingly, there has been provided in connection with this i1nproved dispensing device not only the normal brush cup 38 but also an auxiliary cup l0 which may conveniently be formed integrally with the cup 38 and the main receptacle. This cup is so related to the cup 38 that when the device is partially inverted for filling, the contents of the cup 38 will drain into the cup l0 and will not be spilled.

With certain kinds of adhesives, one of which is known to the trade as hazenite, an air-tight receptacle such as is found in a barometric dispensing device is undesirable because a gas is developed in the hazenite which tends to force the fluid out irregularly into the auxiliary receptacle. This adhesive is viscous and a modified receptacle 42, shown in Fig. 3, is especially adapted for its use. This modified form 42 will be seen to comprise a main receptacle, having a sloping bottom 43, mounted upon the base 44. A cover 46 is provided which is not airtight but will serve to prevent the exposure of themain body of the fluid to sparks or llame. Because of the loose fit of this cover,

it will act as a safety valve to permit the escape of gas liberated by the fluid, thereby ed, as in the form shown in Fi g. l, by means of a cover 58 pivoted to the receptacle and urged to closed position by a spring 60. This cover s retained in open position by means of a latch arm 62 which is provided at its VYouter end with a retaining member 64 atta'ched to the arm 62 by solder having a low melting point. This operation is similar to that described in connection with Fig. l.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. In a receptacle for inflammable fluids, a main receptacle substantially closed to protect the contents against sparks and fire, an auxiliary receptacle connected to the main receptacle and communicating with thc interior thereof, said auxiliary receptacle being adapted to receive a small quantity of the inflammable fluid for removal by the user, a cover for said .auxiliary receptacle I vof the fluid in the main receptacle, a springpressed cover for Said receptacle, a latch arm attached to said main receptacle and provided near its outer end with a retaining linger held in place by solder having a low Vmelting point.

3. A barometric dispensing device comprising a main receptacle, an auxiliary rcceptacle communicating therewith below the normal level of' the fluid in the auxiliary rcceptacle, said main receptacle adapted to be partially inverted for filling, a water cup open at the top and mounted on the exterior of said main receptacle for the reception of a brush when the dispensing device is in normal position and an auxiliary cup connected with the first cup and arranged to receive the contents of the same when the dispensing device is partially inverted for filling.

In testimony whereof I have signed my name to this specification.
